Astronomers discover two intermediate-mass black holes (IMBHs)
First IMBH discovered using data from Hubble Space Telescope and VLT
First IMBH found near Milky Way's center, 0.1 light-years from Sagittarius A*
IMBHs provide insights into black hole formation and evolution
Second IMBH discovered in Omega Centauri, about 17,700 light-years away from Earth
Second IMBH identified using data from 500 Hubble images taken over 20 years
In a groundbreaking discovery, astronomers have identified two intermediate-mass black holes (IMBHs) located near the centers of the Milky Way galaxy. The first IMBH was discovered using data from NASA's Hubble Space Telescope and ESA's Very Large Telescope (VLT), while the second one was found in Omega Centauri, a globular cluster about 18,000 light-years away from Earth. These findings provide valuable insights into black hole formation and evolution.
The IMBH discovered near the Milky Way's center is located approximately 0.1 light-years from Sagittarius A*, a supermassive black hole with a mass of about 4 million solar masses. The researchers noticed an orderly pattern in the motion of stars within a star cluster named IRS 13, which led them to suspect the presence of an intermediate-mass black hole at its center. Further observations using telescopes like the James Webb Space Telescope and the Extremely Large Telescope in Chile are planned to confirm these findings.
The second IMBH was discovered in Omega Centauri using data from 500 Hubble images taken over a period of 20 years. This black hole, which is approximately 8,200 stellar masses and located about 17,700 light-years away from Earth, falls between stellar and supermassive black holes in terms of size. The discovery of this IMBH provides important information about the formation and evolution of black holes in general.
IMBHs are believed to have formed just after the Big Bang and act as 'seeds' for creating supermassive black holes. The first intermediate-mass black hole was discovered in 2020 using Hubble Space Telescope data. These discoveries challenge our current understanding of black hole formation and evolution, offering new opportunities for research in astrophysics.
A rare intermediate-mass black hole was discovered near the supermassive black hole named Sagittarius A (Sgr A) at the center of the Milky Way galaxy by a group of international researchers at the University of Cologne.
The star cluster believed to be the latest intermediate-mass black hole, dubbed IRS 13, moved in an orderly pattern and had to be interacting with Sgr A.

Accuracy
The star cluster believed to be the latest intermediate-mass black hole, dubbed IRS 13, moved in an orderly pattern and had to be interacting with Sagittarius A.
Astronomers have discovered the closest black hole to Earth using the Hubble Space Telescope.
Astronomers at the University of Cologne discovered a second intermediate-mass black hole in the Milky Way, located 0.1 light-year from Sagittarius A*, the supermassive black hole at the galaxy’s core.
Monkeys with high facial expressivity have stronger social connections and are more socially successful.
Accuracy
The cluster IRS 13 exhibits an orderly pattern of movement and unexpected density, leading researchers to conclude that either it is interacting with Sagittarius A* or a gravitational object at its center is influencing the motion of its stars.
Further observations on the intermediate black hole will be conducted using the James Webb Space Telescope and the Extremely Large Telescope in Chile.

No formal fallacies found. There are some informal fallacies in the form of anecdotal evidence and appeals to authority. The author mentions a study from The Ohio State University that uses cats as a model for human obesity, but does not provide direct quotes from the study itself, instead paraphrasing its findings.
] This is not a rerun of last week's roundup; another group of astronomers found a second intermediate-mass black hole in the Milky Way and I can't highlight it. They're cool! They may have formed in the primordial universe, they comprise the seeds of supermassive black holes, and may be formed by the accretion of multiple stars in a cluster rather than through stellar collapse. If there's a third one next week, I'll be irresistibly compelled to tell you. If there's a fourth one after that, I promise to stick it in a footnote.
Cats by the kilogram House cats are a lot like people: They live in a climate-controlled, indoor environment, relax on furniture, and generally have ready access to prepared food. So scientists have come around to the idea that they're a great disease model for human maladies.
Animals share our beds. They share our ice cream. There are all these things that people do with their pets that highlight they are a naturally occurring disease model with similar environmental exposures as humans.
When the cats are on the special diet formulated for weight loss, propionic acid goes up and stays high, and then goes back down when they're put back on the maintenance diet. So it really is a dietary change.
Facially expressive individuals may be better equipped to build and maintain strong social connections, potentially leading to the range of benefits associated with group cohesion, such as increased access to resources, mating opportunities, and protection from threats.
A new study using 500 Hubble images confirms the existence of an intermediate-mass black hole (IMBH) in the Omega Centauri globular cluster.
The IMBH discovered is approximately 8,200 stellar masses and located about 17,700 light-years away from Earth.
This discovery provides valuable information about black hole formation and evolution as it falls between stellar and supermassive black holes.
Accuracy
Astronomers identified the IMBH by observing seven stars that were moving too fast to remain in the cluster without being gravitationally pulled towards its center.

The article contains a few informal fallacies and an example of a dichotomous depiction. The author presents the concept of intermediate-mass black holes (IMBH) as 'middle-child' black holes, which is an informal way to describe these<dummy00015>-type black holes that do not fit into the two known categories. Additionally, there is a slight overgeneralization when the author states that 'astronomers have occasionally spotted a handful of rare black holes that fall somewhere in between these two extremes', implying it's only happened a few times when more instances could exist. The article also presents a dichotomous depiction by contrasting stellar-mass and supermassive black holes, suggesting that IMBHs are the 'middle-child' between them.
Intermediate-mass black holes (IMBH) could provide valuable information about black hole formation and evolution, but only a few of them have ever been spotted.
